Edgar, I have a request. Of the six components of the seeding formula, five are set; the sixth is the November 2009 FIFA ranking. So when we approximate the seeding formula, what we are really trying to approximate is the November 2009 FIFA ranking. You currently approximate the November 2009 FIFA ranking by using the FIFA ranking for the current month. Obviously, as we get closer to November, the FIFA ranking for the current month will more closely approximate the November 2009 FIFA ranking. However, the November 2009 FIFA ranking itself has four components: matches played November 2008 through October 2009 (date-weighted at 1.0), matches played November 2007 through October 2008 (date-weighted at 0.5), matches played November 2006 through October 2007 (date-weighted at 0.3), and matches played November 2005 through October 2006 (date-weighted at 0.2). With your data, you can easily compute the sum of the last three components; the rest of us can approximate the sum of the last three components by dividing a team's November 2008 points by two, but that overweights and underweights various periods (0.25 instead of 0.3, 0.15 instead of 0.2, 0.1 instead of 0). You can also compute the rating points for the matches between December 2008 and the current date, and simply weight them at 1.0; alternatively, you can weight them at 1.0, divided by 12, multiplied by the number of months of ultimately-1.0-weighted rating points that we have available. Either of those procedures would seem to approximate the November 2009 FIFA rankings more closely. (Also, if you published both the fixed sum-of-the-last-three components number and the current final-component number, it would be easier for the rest of us to speculate on what rating points a team will ultimately get.) Obviously, weighting just results from December 2008 at 1.0 would be silly to try in January 2009 (estimating a team's results for twelve months on the basis of one month), but now that we have seven months of results, it should work better. The problem with using, say, the July 2009 FIFA ranking to approximate the November 2009 FIFA ranking is that it overweights matches between August 2008 and October 2008. Those matches will ultimately be weighted at 0.5, but in the July 2009 FIFA ranking, they're weighted at 1.0. I realize from your web site that you have ambitions to do something more with this data than just satisfying the curiosity of BigSoccer readers. Also, you are clearly spending a lot of time and effort in coming up with your figures, and my request involves sharing more data than you might be comfortable sharing. But if you're up for it, I'd love to see the numbers.
